PUMP.

Application filed May 24, 1918.

To aZZ whom it may concern Be it known that I, JOHN A. GoeoLINsKI, a subject of Russian Poland, residing at Drissa, in the District of .Vitebsk, Russia, have invented a new and useful Improve ment in Pumps, of which the following is a specification.

Theobject of this invention is to provide an improved pump suitable for circulating the lubricating oil in an engine of any type, inclusive of the internal combustion type.

The accompanying drawings show two forms of embodiments of the invention.

Figures 1, 2, 3 and 4 show, in different positions, a single unit containing the invention.

Fig. 5 shows a vertical section of the invention applied to a plurality of pumps operated as a unit.

Fig. 6 shows a section of the same on the line 6-6 of Fig. 5.

Fig. 7, 8, 9 and 10 are details of the same.

Referring to Figs. 1, 2, 3 and 4i, p and p are portions of a casing containing the inlet ports a, a, and outlet ports Z), 6. e, e are pump, cylinders in alinement with each other provided with the laterally extending flanges e 6 c is a rigid rod carrying the pistons 0, c and provided with an eye 0 in which the crank pin d of-the crank tZ operates. The heads of the cylinders are provided with the openings 0* and c which have a valve cooperation respectively with the ports a, Z) and a, Z), as the cylinders are slid laterally by the movement of the crank on the opposed surfaces of the casing 19, p. In Fig. 1, the crank 1s shown on its dead center in line with the axis ofthe cylinders,

the ports being closed and the cylinder 0 charged with oil. A movement of the crank 90 in the direction of the arrow, as shown in Fig. 2, shifts the cylinders c, e to the left of the axis of the shaft, opening outlet port Z) to cylinder 6, and inlet port a to cylin der c. A. further movement of 90 in the same direction, closes all ports and charges the cylinder 0 with oil, as shown in Fig. 3.

A further 90 movement of the crank shifts the cylinders to the right of the axis of the shaft, opening cylinder 6 t0 inlet a and cylinder 6 to outlet 6.

Figs. 5 and 6 show a plurality of the above described pumps operated as a unit. P is a casing to which a cover is hermetically fixed, forming a reservoir into which oil is fed through the opening Q (Fig. 7). The inner faces of the casing walls 19, 1) are fin- Specification of Letters Patent.

partly in section in Fig. 5. 3 The cover 7 is provided with a central opening forming a bearing for the hub 72. of the pinion h, rotating within the reservoir and which is actuated by a worm 2' on the shaft c" journaled in the cover 7 (Fig. 7). The hub of pinion ZL is provided with an eccentric pin j on one side, and a concentric stud j on the opposite side. The stud j extends through the wall of the hub and carries on the outside a knurled knob 7c fixed to it, and secured by a nut k. A coiled spring 71: is interposed between the disk j and the wall of the hub. The eccentric j enters an opening in the bar at, to which are fixed a nun1- ber of rods or pistons at extending an equal distance on both sides of the bar, and adapted to cooperate with cylinder bores in the blocks Z and Z.

As seen in Figs. 5, G and 7, the rotation of the pinion it causes pin j to reciprocate bar on which actuates the blocks Z andZproducing movement of the pistons 91 in their cylinders. At the same time it slides the blocks Z and Z on the casing p and p, and causes a valve cooperation between the openings in the heads of the cylinders and the inlet and outlet ports a, a andb, Z), similar to that described for Figs. 1, 2, 3 and 4.

Springs .9 and s set in recesses in blocks Z and Z maintain the same in frictional contact with the faces of the casing walls. The base of the knob Z1! is provided on its perlphcry with a number of recesses 1' cooperatingwith the pin 0.

When the knob is is lifted out of engagement with the pin 0, it may be turned and seated again at the desired adjustment where it will. be held under the tension of the spring if. By this adjustment of the eccentric pin j, the stroke of the piston 76 may be increased or diminished, and the quantity of pressed oil increased or diminished during each cycle. Thus full regulation of the quantity of the expulsed 011 from zero to the maximum is obtainable.

In Figs. 5 and 6, twenty cylinders in all are indicated, ten with their axes in one plane, and ten with their axes in a plane parallel therewith. Each block Z and Z contains ten cylinders.

It will be observed that in the above illustrations of my invention, the pistons of opposite cylinders are coupled rigidly together by the interposed rods, and are operated from a single regulated crank by a turning eccentric; both the piston action and the valve action being transmitted from the crank or eccentric through the rod connecting the opposed pistons. It will also be seen that in the construction shown in Figs. 5, 6 and 7, the casing which is designed to contain the pumps, the driving and other mechanisms, is also part of a reservoir from which the oil which surrounds the pumps etc. may be distributed through pipes connecting-with the respective pumps.

i I have above described the form in which I prefer to embody my invention at the present time, but said form is susceptible of wideyariation without departing fromthe principle of my invention.

hat I claim and desire to secure by Letters Patent of the United States, is

1., In a pump, in combination, two stationary parts containing inlet and outlet ports, two inversely arranged cylinders sliding upon said parts and containing openings to cooperate with said ports, pistons within said cylinders connected by a rod, and means acting on said rod whereby longitudinal and lateral movement is given to the pistons, and

; lateral movement to the cylinders.

2. In a pump, in combination, two inversely arranged cylinders in axial alinement, parts containing inlet and outlet openings upon which said cylinders are slidably mounted, pistons within said cylinders and 'means whereby longitudinal and lateral movement is given to the pistons, and lateral movement to the cylinders.

3. In a pump, in combination, series of axial alinement with the first series, pistons within said cylinders, rods connecting said pistons, a cross member'con nected with said rods, means imparting to said rods both longitudinal and lateral movementwhereby the pistons are moved longitudinally and the cylinders laterally, and the casing containinginlet and outlet ports cooperating with openings in said cylinders.

4L. In a pump, in combination, a casing, a.

reservoir inclosing parts of the pump, inlet ports connected therewith, and outlet ports, inversely arranged cylinders slidably mounted in said casing and having openings rooperating with said ports, pistons within said cylinders, a rod connecting said pistons, and means whereby said rod is given a longitudinal movement to operate the pistons in the cylinders, and a. lateral movement to slide the cylinders on said casing.

5. in a pump, in combination, parts .l'acing each other provided with inlet and outlet ports, a block slidably mounted on each of said parts, a plurality oi cylinders formed in each of said blocks, those in one block alined with those in the other, pistons within said cylinders, a rod connecting each piston with its opposite and means whereby said rods are moved longitudinally 2 nd laterally.

6. In a pump, in combination, a series of slidably mounted cylinders. another slidably mounted series arranged inversely and in axial alinement with the first series and pistons within said cylinders, rods connecting said pistons, a cross member connected with said rods, and means imparting to said rod both longitudinal and lateral movement whereby the pistons are moved longitudinally and the cylinders laterally, the casing containing inlet and outlet ports cooperating with openings in said eylinders and means for regulating the stroke oi the pistons and the quantity of oil expulsed.

In testimony whereof I have hereunto signed my name in the presence of two subscribing witnesses.
